The effects of M0O3 addition on the carbothermal reduction of fine Ti02 were studied for obtaining nano-powders and for understanding the mechanism of the carbothermal reduction. Ti02 was mixed with C powder and M0O3 powder. The mixed powder was heat treated in a rotary tube furnace up to 1773 K. The results indicated that the particle size of Ti02-Mo03-C powder heated in the rotary tube furnace was comparable to that heated in batch-type furnace. The CO gas concentration during the carbothermal reduction of Ti02-Mo03-C powder was measured. It was confirmed that the reduction temperature of titanium oxide decreased with an addition of M0O3.
